Wilcoxon rank-sum tests showed that there were no significant differences between the unilateral and bilateral groups in the number of trials (p = 0.59), the duration (p = 0.22), the number of rewarded trials (p = 0.84), or the reaction time from the go-signal (p = 0.9), although the difference in the ratio of rewarded trials was marginally significant (p = 0.06). c-Fos-positive cell density maps Figure 3 shows c-Fos-positive cell density maps (PCDMs) at five levels for each of the three task groups.
